The front brake pads are showing extremely uneven ware. Outer brake pad is at 2mm and the inner is at 7mm due to a spring issue on the front caliper. There is also a lip on the left rotor. The tech used 25-na-365 to help identify the issue. However, my VIN is not covered under this repair. The result is a $500 out of pocket repair for something that should be a mfg defect and not wear and tear. As this was already outlined as an issue with other 2024 chevy Colorado's I am asking this to be expanded to cover my vehicle as well. The issues was also causing my brake sensors to "detect" new brakes and I had to inform the vehicle that I have not had brake service done to trigger this alert.

On Sep 14th 2025 with km 41959km, after turn on my Colorado, after I filled the fuel tank, I had driven more of 50 min, a message appears in the screen control: failed braking system 100km/h max velocity and a second message appears: provide service to esc. Then turn off the Colorado, wait some seconds and turn on again, no messages appears. So I continue driving normally until Dec 21st 2025 with km 47200km driving on a boulevard, I did stop two times due to traffic, automatic start/stop activate, in the second stop when start on again same message appears: failed braking system 100km/h max, I felt the brakes not responding, my Colorado stopped over a greater distance. If I hadn't maintained a safe following distance, I wouldn't have been able to stop in time and I would have crashed into other vehicle. I arrived on home safe but nervous. At next day, Dec 22th turn on my Colorado and appears same message, km 47245km I turned off and tried turn on again but it not turn on, battery low message appeared, then I had to have my Colorado towed to the car dealership. It is on revision waiting a diagnosis. I hope you can analysis this issue. Thanks.

Visibly observed antifreeze / coolant leaking from top radiator hose where it connects to the radiator. Dealer replaced upper radiator o-ring but it's still leaking. At 17000 miles a service brake warning message showed up on information screen. Front brake rotors are warped. Dealer states normal wear on front brakes. Also the dealership stated the front left inner brake pad was down to 2mm of pad left. Wanted over $420 to turn rotors and replace pads. I inquired why the left front pads were worn so much than the right side. They stated this was normal!.

I was driving down a hill and hit my brakes and the pushed back against me and then went right to the floor with minimal braking. I got an error message on my dash that said “brake system failure- do not exceed 62 mph” luckily it was early in the morning and nobody was in front of me. All of the lights were green and between the engine braking and the little brake power that I had I made it up the hill (about a mile) to the chevy dealership. I got an error notification the day prior that said there was an electrical error and my check engine light came in. I drove straight to the dealership but they couldn’t do anything since it was 4:30 and later than work hours so they made me an appointment for the next day and let me go. They told me later that day that it was an issue with the master cylinder (which with some research I found that there is an active lawsuit against this issue) I was issued a loaner vehicle with a crack straight across the entire windshield (it was all they had available and I was told it would be “okay” so I’m fine with that).

Component failure: body control module causing systematic electrical failures: door locks, power windows, window regulators, four-wheel drive transfer case display. Components intact, available for inspection. Safety risk: door locks malfunction preventing emergency exit. Power windows fail affecting communication/egress. 4wd display fault (yellow auto vs white) indicates transfer case control issues affecting traction in mountain winter driving at 10,000ft elevation. Unpredictable electrical failures create safety risk during remote travel. Dealer confirmation: approximately 20 dealer visits. Each time: scan codes, test drive, "no fault found. " problem temporarily clears via battery disconnect/reconnect, proving electrical fault not mechanical. Dealer cannot diagnose root cause, hasn't performed systematic electrical testing. Manufacturer inspection: none despite repeated failures. Warning symptoms: intermittent: door ajar warnings, power window/lock failures, 4wd indicator yellow, various warning lights. All symptoms simultaneously resolve after battery disconnect/reconnect, indicating bcm or power distribution fault. Pattern repeats with increasing frequency. Critical: research shows multiple 2023 Colorado owners report identical patterns - intermittent multi-system failures resolving via battery reset. Indicates systematic 2023 model year defect, likely bcm firmware/hardware issue. Problem occurs unpredictably, clears during dealer transport. Request gm engineering data logging during normal operation.

This is the fifth vehicle with the 2. 5l engine that has experienced vacuum pump failure resulting in a broken exhaust camshaft. Without warning, drivers have experienced a complete loss of brake function as a result of the vacuum pump failure.

Vehicle: 2023 Chevrolet Colorado trail boss mileage: approximately 14,000 miles I am submitting this complaint because the abs braking system on my vehicle activates unexpectedly and causes a temporary loss of braking when driving over uneven pavement. When braking over potholes, bumps, or rough road surfaces at low to moderate speeds, the abs system engages even though traction is available. When this happens, brake pressure is reduced to the point where the vehicle does not slow as expected. The abs warning indicator flashes briefly, and there is a noticeable delay before normal braking resumes. This behavior has occurred multiple times in normal driving conditions on city streets, not during panic stops or slippery conditions. The issue feels most pronounced when approaching intersections or slowing in traffic over broken pavement, where consistent braking is critical. The momentary reduction in braking force significantly increases stopping distance and creates a safety concern. The vehicle has low mileage, has not been modified, and is maintained as delivered from the manufacturer. There are no warning lights remaining on after the event, and the issue appears to be related to abs calibration rather than driver input or road conditions. This does not feel like normal abs operation and gives the impression that braking is interrupted at the exact moment it is needed. Given the frequency and repeatability of the issue, I believe this represents a potential safety defect that could contribute to a collision, particularly in urban driving environments with uneven road surfaces. I am submitting this complaint to document the issue and to request that the abs braking behavior on this vehicle be reviewed for safety.

The contact owns a 2021 Chevrolet Colorado. The contact stated that while driving at an undisclosed speed, the vehicle shuddered and failed to decelerate as intended while the brake pedal was depressed. An unknown message was displayed. In addition, the contact stated the vehicle failed to respond properly while the accelerator pedal was depressed. Upon inspection, the contact noticed an abnormal engine oil leak. The vehicle was towed to the residence. The vehicle was later towed to a local dealer, where it was diagnosed with an exploded brake booster and metal shavings inside the engine. The vehicle remained at the local dealer unrepaired due to the cost. The local dealer could not guarantee that the repairs would correct the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 70,000.

I have experienced brake failure twice while driving my 2023 Chevrolet Colorado. When the failure occurs, the dashboard displays multiple warnings, including “service traction control,” “service power steering drive with care,” and “no assist soon. ” when these messages appear, the steering becomes extremely stiff, the brakes lose stopping power, and the vehicle becomes very difficult to control. The first incident happened around April 2024, and the dealer performed a software update. The issue happened again around October 2024 at approximately 24,000 miles. The vehicle is primarily used on highways and has no modifications. This is a serious safety concern. The combination of brake loss and power steering failure could result in loss of control, crash, injury, or death. There was no warning before the failures occurred. The dealer cannot confirm a permanent fix. This problem needs to be investigated for a potential recall. This vehicle is now unsafe and unreliable. I refuse to transport my family in it. I am seeking a full refund/buyback, as multiple safety system failures are unacceptable and dangerous.

Today while driving my brakes got super hard. Had to use my entire weight to get it to stop and still was moving forward. Had to use the emergency brakes and a prayer. Luckily I wasn’t on the highway or it would’ve been a deadly accident. When I opened the hood the camshaft sensor was broken loose. Mind you I had taken the truck to the dealer a while back for a rattling noise at 1500 rpm and they couldn't figure out the issue. They replace the catalytic converter under warranty. But kept making the same noise around the same rpm. Obviously it wasn't the converter. My truck has 43,136 miles only. 2021 Colorado 2. 5 luckily I’m alive today but this must be taken care of as soon as possible. I read a lot of Colorado’s seem to have the same issues. Needs a recall.

I was on my way home from work and I was on highway 16 in washington state near port orchard and I was driving 64mph and all vehicles in front of me were all breaking slowing down pretty fast and when I pressed down on my brakes the brakes were totally stiff I could not stop and had to drive on the side of the road and passed 20 plus cars and was finally able to come to a stop. If I had no where to go I would’ve hit the car in front of me at a high rate of speed potentially causing a major or deadly accident. They were working fine 5 minutes before that. I think it is a major issue that will cause fatalities in the future if this problem isn’t taken care of. I’ve never had a vehicle do this and I’ve been driving for 38 years.

Happened twice now while driving, power steering suddenly lost and two messages on dash: loss of power steering and stabilitrak. Pulled over and turned off ignition. When restarted all errors automatically cleared and systems appear to be functioning correctly. Steering without power assist is very difficult and high safety concern at low speed driving.

Intermittent break failure service dealer could not duplicate contacted GMC they say call back if it happens again.

October 2025----problem with 2017 Chevrolet Colorado wt with 2. 5l engine and 6 speed automatic. It has 57,000 miles on it. Original owner--bought new. "stabilitrak" warning light came on when I first started the pickup in the morning and stayed on. Then a message appeared saying that there could be a steering issue or a control issue operating the pickup and to take it to the dealer for service. Colorado starts normally and runs normally. Only issue is the warning light for the stabilitrak is on constantly. I read in the manual that tcs(traction control system) and the stabilitrak system have been disabled. The owner's manual states "the vehicle is safe to drive; however, you do not have the benefit of stabilitrak, so reduce your speed and drive accordingly. " have a dealer service the system. I have had no safety issues or risky situations. Have about 300 miles added since it occurred. It has not been inspected yet by a dealer.

At engine start up there were two warnings that came up on info screen. "service front brake monitor" and "front brake pads low". Just before this incident the monitor showed front pads at 82% brake life and the rear pads at 84%. Upon my own inspection the driver side front brake pads are worn significantly more than the passenger side. Front brakes are also squealing when coming to a stop. Chevrolet dealership inspection/repair scheduled for 9/22/25.

I have had 3 separate occasions where the automatic emergency braking has engaged with nothing in front to trigger it. Each time was one a busy section of road, two of those times I had traffic behind me nearly causing an accident.

Many warning lights are on for traction control, abs , brakes service esc, trailer braking and the adaptive cruise control system is not working, it was reported to the dealer, they checked it said bad battery, they coded it out said it is fine now on 9/5/25. It’s back at the dealer with all the same warnings on again.

On the day of purchase, while driving on a freeway, the vehicle would not accelerate. The rpm's went up, the engine revved, but the vehicle acted as if it was in neutral. These vehicles will not accelerate if they think the brake pedal is also being pressed. The brake was not being depressed. As I was pulling the vehicle to the side of the road, suddenly it allowed me to accelerate again, and I continued with no further issues. One week later, with fewer than 200 miles on the vehicle, upon starting the dashboard showed alerts to service esc, service brake assist, service trailer brake system. The abs and traction control lights also came on. These are all systems designed to prevent loss of control, and all failed without warning. A dealer service center diagnosed this as a known problem with a faulty master cylinder, on several models built over a period of several months.

Last Wednesday evening I purchased a 2025 Chevrolet Colorado zr2 midnight edition from preston hood Chevrolet in crestview, florida. I had been waiting to see this truck for a couple days as it was listed on their website. They said it was in service but when I asked why they did not tell me. When I went to the dealership to buy it I asked again why it had been in service and the salesman said he did not know but he said this truck has a lot of accessories they had to put on it. I drove the truck home, and then to work the next day and in my way home the brake system completely failed. I kept pushing fully on the brakes and it kept going and took quite some time to stop. I noticed multiple brake warnings and was stranded on a very busy street with cars flying by. This was not a safe area. When I called the dealership I asked point blank if the brakes was the reason I was unable to see the truck for the days I was waiting to purchase it and he said yes. The car was towed to a close by chevy dealership. (sandy sansing Chevrolet) and my husband drove me back to preston hood ( the selling dealership) and explained that I would never feel safe in that truck again as the incident scared me more than anything I can remember. I wanted my trade in back and the deal reversed primarily because they lied to me about why the truck was in the service department. I would have never considered purchasing a vehicle with brake issues. I asked for the prior service records and they had already changed the master cylinder and other items. The next day after many phone calls they finally gave me my trade back. I am not reporting for any personal gain, only to help keep someone else from getting killed by this obvious known issue with this truck.

This truck was purchased may 2025 and currently has 2600 miles. Without any warning the brake light and abs warning lights came on along with messages reading brake assist,esc, and trailer brake require service. I took my truck in to a Chevrolet dealer on Aug 18, 2025 for inspection of issue. I was informed the master cylinder has failed and because this was a “safety” issue I could not take drive my truck and they would not allow me to remove the vehicle from their lot. I understand there has been many people with this same issue. Why has a recall not been issued? why is Chevrolet still selling these trucks? this needs to be addressed ASAP to save lives.

The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving on a service road at 35 mph and attempting to bring the vehicle to a stop, the brake pedal was depressed; however, the brake pedal was extremely firm, requiring excessive force to depress for the vehicle to come to a stop. The contact stated that there was an abnormal amount of white smoke coming from the front end of the vehicle. There was no warning light illuminated. The contact pulled over and had the vehicle towed to the local dealer to be diagnosed. The contact was informed that the vacuum pump was faulty and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 141,540.

When you have your foot on the break engine running within about 5 mins the breaks release for a second all the light on the dashboard kick on then the breaks feel spongy, you have to then turn the truck off the computer resets check engine light will still remain but the breaks will now be functional again. When taking it to the dealer they stated there was a software recall and they reset the light called it a day.

From auto stop when engine turns back on it jerks me forward.

Started the vehicle and 4 dash lights were on. The abs light, the forward collision system light, the brake light, and the traction control light. The vehicle was taken to a dealership and we have been notified by the dealer that it is a master brake cylinder failure. The part is on national backorder with no eta. Luckily, it did not fail while driving, but could've been tragic. This vehicle is brand new and belongs to my 16 year old. This is a known issue on the Colorado, traverse, and possibly other models. However, I have yet to find a recall or TSB. Brake cylinders are failing in brand new vehicles and gm needs to address it.

The contact owns a 2023 Chevrolet Colorado. The contact had taken the vehicle to the dealer for a routine oil change and after the vehicle was serviced, the contact was provided a multi-point vehicle inspection sheet which showed that the brake pads had received a green check mark and that the brake pads were 7-millimeters or greater on both the driver’s and passenger’s side. The next day upon start of the vehicle, the contact stated that a message "new brake pads detected" question was displayed on the instrument panel. The contact selected the "no" option followed by another question to service the brake pads. The contact then stated that a "service brake pad monitoring system" message appeared on the instrument panel. The vehicle was taken back to the dealer where the dealer was informed of the messages. A mechanic inspected the vehicle and informed the contact that both the brake pads and rotors needed to be replaced. The contact was also informed that the brake pads were 2 millimeters or less, despite the contact receiving information the day prior which stated otherwise. The contact questioned the dealer about the discrepancy and was informed that the computer provided the results for the multi-point vehicle inspection. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 27,000.

I have been having intermittent issues with a warning on dash says service safety retrain system vehicle will shut off on its own doesn't want to restart vehicle was taken to dealership for a TSB as well as the shutoff issue they had the truck 28 days said they diagnosed the truck could not duplicate my concerns I also explained the issue with display going out flickering brake lights etc, intermittent issue with btakes being hard then extremely soft, I even showed video that they can clearly hear me talking on they did not care. When I picked the truck up from dealership the mileage in was same as mileage out as noted on the paperwork and matches pictures I took they never drove the truck. On Wednesday June 4, 2025 while driving home I ended up running a stop sign and barely missing a car because truck shut off causing my brakes to not respond I was able to get it to stop just in time it was witnessed by a local law enforcement agency I showed the officer my truck would not start and pedal was unresponsive was told it had to be towed had a friend tow to my house. On Saturday June 14, 2025 while on my way to northern duchess hospital the warning came on the display and vehicle shut off I was able to get it off the road could not start it had to call for someone to drive me to the hospital upon release at 5am I had to call my brother to pick me up we got truck to start after 20 mins while driving it he informed me I had no brake lights turn signals or headlight the display was black no speedometer nothing had to call friend to tow again once at my house he started checking fuses found 4 melted fuses one was ecm the others were body control module and something else this truck has 7300 miles on it the problems are getting worse last time at dealership service manager stated he wasn't wasting more than 20 minutes on diagnosing anything. Other issues are windows going down on there own climate controls coming on by itself and air coming in by top of windshield.

Vehicle shaking very badly when braking. Then “service brake monitor” message displays. Took it to a chevy dealership who said my rotors were warped. Turns out many people are complaining about it on reddit. I purchased vehicle with less than 20k miles on it and it was a chevy certified used vehicle. I don’t feel safe driving it and chevy will not foot the bill. This could potentially be dangerous for other drivers and my guess is the parts are defective or something other than “driving conditions” are at play. This should not be happening!.

Chevrolet Colorado slows down for no reason.

Forward collision braking activated for no reason and will hard brake. Has done it in the middle of an empty parking lot as well as when driving 65 mph down the highway, twice. No major injuries happened either time other then sore necks and seatbelt marks. On 2 incidents only the driver was in the vehicle, the other incident consisted of the driver, front seat passenger and 2 children in the back seat. The vehicle has been inspected by dealership. The vehicle now has brake and router problems, which the dealership has said is from hard braking. The vehicle has a bad vibration when applying the brakes.

The right front brake caliper failed with 15747 miles. Local dealer made repairs and said the caliper was not the cause. Their cause was blaming a brake controller used in towing the vehicle. If the controller had caused the failure more than one wheel would of been effected. The three remaining wheels all showed fine and had over 7mm of brake lining remaining. The wheel effected had zero pad remaining. I have replaced parts in my possession for evidence.

-what component or system failed or malfunctioned, and is it available for inspection upon request? 2016 Chevrolet Colorado VIN: [xxx] engine: 2. 5l i4 (camshaft-driven brake system assist vacuum pump failure). Gm technical service bulletin 21-na-268 (Nov 2021) confirms that if vacuum pump drive lugs are broken, replacement of both the vacuum pump and the exhaust camshaft is required which was the case. Parts kept by repair facility that performed service. Autonation Chevrolet south clearwater FL 33764. -how was your safety or the safety of others put at risk? may, 2025 the vehicle experienced a sudden loss of braking (hard/stiff brake pedal). This is a safety-critical failure. -has the problem been reproduced or confirmed by a dealer or independent service center?yes by shop stated above. Diagnosis showed a seized engine brake system vacuum pump (driven by the exhaust camshaft) that had sheared drive lugs and produced metal debris which damaged the exhaust camshaft and associated components. The repair required replacement of the vacuum pump and the exhaust camshaft; my total repair cost was over $4,000. The camshaft was not readily available and I required a rental car for over 30 days while waiting for parts. -has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? system and parts inspected by shop above. Gm special coverage n182202780 (Apr 2019) addresses vacuum-pump related decreased brake assist for certain 2014–2017 gm trucks/suvs, but Colorado is not listed in that bulletin’s model list. -were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? check engine came on at time of brake loss (brake vacuum pump failure). Immediate system failure. I request NHTSA send me a copy of any investigation number or record created for this complaint, and I request guidance on whether I may be eligible for reimbursement under any gm program. Information redacted pursuant to the freedom of informatio.

When battery was beginning to get old/need replacement but vehicle would still start: 1. The power steering assist stopped working intermittently (virtually impossible to steer even at speed) 2. Power brake stopped working intermittently (very hard to get vehicle to stop) unsafe for me, would have been very unsafe for certain without significant physical strength.

Brake pedal went to the floor when I applied the brakes, took truck to dealership. Dealership reported to me the master clylinder was defective and needed to order one from detroit.
